TL;DR: The "gas out-gas in" method can directly determine the volumetric mass transfer coefficient in a bioreactor system and provide estimates of thevolumetric microbial oxygen uptake rate and the average oxygen saturation concentration at the gas-liquid interface.
Abstract: There are many dynamic methods for measuring the volumetric mass transfer coefficient. The “gas out–gas in” method can directly determine the volumetric mass transfer coefficient in a bioreactor system and provide estimates of the volumetric microbial oxygen uptake rate and the average oxygen saturation concentration at the gas–liquid interface. The errors on these parameters are large if the dissolved oxygen probe response time is not considered. For reliable measurements, deconvolution of the oxygen probe measurements must be made. © 1995 John Wiley & Sons, Inc.

TL;DR: Pure component adsorption equilibrium and kinetics of SO(2), NO, and CO(2) on zeolite NaY, NaX, CaA were obtained respectively and results suggest that Adsorption affinity follows the trend SO (2)>CO( 2)>NO for the same adsorbent.

TL;DR: The aim of these experiments is to study the oxygen mass transfer rate through the mass transfer coefficient, kla, for a stirred bioreactor and different fermentation broths, using a large domain of operating variables, using MATLAB software.

TL;DR: In this article, it was shown that under certain conditions partially wetted surfaces yield practically the same drying rate as entirely wetted ones, and that less than 1% of the surface needed to be activated in order to give the same reaction rate such as an entirely activated one.

TL;DR: In this article, the authors investigated the characteristics of the gel layer of polyvinyl alcohol and ovalbumin aqueous solutions, using cellulose acetate tubular ultrafiltration membranes.
Abstract: Characteristics of the gel layer were investigated by direct measurement of its concentration treating polyvinylalcohol and ovalbumin aqueous solutions, using cellulose acetate tubular ultrafiltration membranes. The concentration of the gel layer was not constant but a function of bulk concentration and feed velocity. The mass transfer coefficient obtained agreed with Deissler correlation. There was a definite correlation between the resistance of the gel layer and its concentration.
